Heating of a Molecular Cloud by a Primordial Black Hole
Abstract
The heating of a molecular cloud by photons emitted by a primary black hole (PBH) located inside the cloud is considered. For graphite and silicate dust particles, the dependence of dust temperature on the distance from PBH is derived, along with the emission spectrum of dust particles. The obtained spectrum is compared with the sensitivity of the Millimetron Space Observatory for various values of concentration and size of dust particles and different PBH masses.
